For those of you who use Roon, it seems like there is an issue with the current build related to adding new music. In the past, when you added new files to a storage location Roon would scan those files and add them to your library. The new issue results in Roon reporting I/O errors (you can see this in the “skipped files” section under storage). The files will not be added to your library unless you close Roon server and then restart it. Roon support is aware of the issue and has flagged it but I have not seen a resolution yet.
